Hi S&J
The largest dia wheel that holden produced that suits the early Holden 108 PCD is the 14 inch rim for HK, HT, HG.
Yup... Early Volvo have the same pattern .. not sure if they came out in 15 inch .. early Holden guys use these rear ends in EH's etc as they where a disc brake rear end.
There is a few companies here i OZ the can supply larger diameter wheels with whatever centre stud patterns you want.
I think "Mr Lugnuts " in VIC is one Not sure if he still exists??..03 97376330
.. Nearly sure thats where i ordered the rims and centres ( seperately ) for the black 54 Effy i had. Had to machine the centres down to fit in the barrels .. then professionally weld them to suit the F100 offset.
There is a Co in Tweed Heads that builds Rods ... They also do specialised wheels. Have seen their website but cant think of their name??
Fat lot of help i am
Will ask the mate over at Edgeworth that builds rods what the company name is and get back to you.
He orginally steered me on to them when i mentioned i was looking for an early Chev Panel Truck.
Anyway guys .. Try Mr Lugnuts....... if ya have no luck there ...have a bit of a google and see what ya come up with.
Hope this helps
Reddo... as vague as ever.
